Scholastic Book clubs are wonderful! 

I've used them for over 24 years and have found wonderful literature at costs far less than big name bookstores.  Below you will find the link to set up a parent account and begin ordering online.  It's quick, it's easy, and it's safe! 
I will also be sending home an order form each month starting next month. Take a look at them.  Try and select books on your childs AR level so they may use them for pleasure and also apply toward goals.

Follow the directions on the site to set up a parent account (just click on parents).  You'll need the activation code to access my account.  The rest is a piece of cake!
Our classroom activation code is:
